I've used a Rumpsters before and unless they changed the design they do not have a pocket, they have two quick dry flaps attached to the edge of the diaper which they say you can stuff an insert under like a pocket but it would have to be a REALLY thin insert. They fit very trimly and are super cute, but I had a print one and had major problems with wicking, I've heard that the solid colors are better, but they are not a good diaper for heavy wetters. HTH
